Text linguistics, though firmly based on all precedent work in sentence linguistics, is not a mere extension of the methods of the latter to units above the sentence; it adds a new dimension to linguistics, which may affect our thinking about any aspect of linguistics. In this paper the concept of text is applied to the linguistic analysis of selected haiku. These poems are examined from three perspectives: (1) being "a" text, the demarcation of one text from another; (2) having the quality of being "text," the aspect or function of language that constitutes this; and (3) having the structure of a text. Peripheral topics, such as mixed texts, informant texts, and decontextualized texts, are also discussed. (DB)
